A compression storage bag is provided, in which a suction equipment such as a vacuum cleaner can be used, or in some cases the compression-storing operation can be done manually without using a suction equipment, as appropriate, depending on the kind and number of the goods to be stored, and depending on the circumstances of the compression-storing operation. The compression storage bag includes a storage bag main body, which has an entrance-exit portion (or an opening portion) on one side, for putting in and taking out goods to be stored. The opening portion is made open-close free, by open-close means. The compression storage bag has a first non-return valve on the opposite side of the opening portion. This first non-return valve is provided with one side extending to the inside of the storage bag main body, and the other side extending to a path that connects communicatively with the exterior of the storage bag main body. Moreover, the compression storage bag has an outlet, which makes it possible for the air inside the storage bag main body to flow out through the first non-return valve and the path. In particular, a second non-return valve, which has an opening portion through which air is sucked out of the interior of the storage bag main body, is formed at a different place from the first non-return valve.
